IMPROVEMENT IN SULKIES.

Specification forming part of Letters Patent No. 144.983, dated November25, 1873; application filed October 24, 1873.

To all whom it may concern:

Be it known that I, LA FAYETTE H. J ENNI- SON, of Monroeville, county ofHuron and State of Ohio, have invented a certain new and ImprovedTrotting-Sulky, of which the following is a full, clear, and completedescription, reference being had to the accompanying drawings makingpart of the same.

Figure l is a plan view of the sulky, or so much thereof embracing theinvention. Fig. 2

- B O D, the cross ties or bars, and E the axletree stock. The thillsare attached to the axle-tree, and s" giported above it by thespringbrackets F. Between the rear end of each of the thills and theaxle-tree is interposed a U- shaped spring, G,'directlyover which issecured the drivers seat. The relative position of the springs to theframe of the sulky is such as is'shown in the drawings.

The U-shaped springs referred to are made of hickory wood. Thatmaterial, being light, tough, and not liable to break abruptly orshortoff, is preferred for these springs to metal. Steel springs,however, may be used, it extremelightness is not to be considered in theconstruction of the sulky, which, for trotting purposes, is an importantpoint, as the utmost lightness is required consistent with sufficientstrength for safety.

The brackets F are also made of wood, which are sufficiently large tosupport the thills and driver, and at the same time light enough to beserviceable as springs.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

1. The U-shaped springs Q, in combination with the thills A A andaxle-tree E, substantially as and for the purpose set forth.

2. The spring-brackets F, in combination with the thills A A andaxle-tree E, as and for the purpose set forth.

3. Thetrotting-sulky consisting, essentially, of the thills A A,U-springs G Gr, springbrackets F, and axle-tree E, all constructed andarranged in the manner as described, and for the purpose set forth.
